Chrysanthemum plant named ‘Yodanielle’

ABSTRACT

A distinct cultivar of Chrysanthemum plant named ‘Yodanielle’, characterized by its upright, mounded and rounded plant habit; freely branching habit; dense and full plants; uniform and freely flowering habit; decorative-type inflorescences; light purple-colored ray florets; and natural season flowering in mid-October in the Northern Hemisphere.

BOTANICAL CLASSIFICATION/CULTIVAR DESIGNATION

Chrysanthemum×morifolium cultivar Yodanielle.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium, commercially known as a garden-type Chrysanthemum and hereinafter referred to by the name ‘Yodanielle’.

The new cultivar is a product of a planned breeding program conducted by the Inventor in Salinas, Calif. and Alva, Fla. The objective of the breeding program is to create new garden-type Chrysanthemum cultivars having inflorescences with desirable inflorescence forms, attractive floret colors and good garden performance.

The new Chrysanthemum originated from a cross made in December, 1996, in Salinas, Calif., of the Chrysanthemum cultivar Barbara, disclosed in U.S. Plant Pat. No. 8,607, as the female, or seed, parent with a proprietary Chrysanthemum selection identified as code number 93-L591002, not patented, as the male, or pollen, parent. The new Chrysanthemum was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross grown in a controlled environment in Alva, Fla. in November, 1999. The selection of this plant was based on its desirable inflorescence form, attractive ray floret color and good garden performance.

Asexual reproduction of the new cultivar by terminal cuttings taken in a controlled environment in Alva, Fla. since January, 2000, has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Yodanielle has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Yodanielle’. These characteristics in combination distinguish ‘Yodanielle’ as a new and distinct cultivar:

1. Upright, mounded and rounded plant habit.

2. Freely branching habit; dense and full plants.

3. Uniform and freely flowering habit.

4. Decorative-type inflorescences.

5. Light purple-colored ray florets.

6. Natural season flowering in mid-October in the Northern Hemisphere.

In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plants of the female parent, the cultivar Barbara, in the following characteristics:

1. Plants of the new Chrysanthemum were larger than plants of the cultivar Barbara.

2. Plants of the new Chrysanthemum flowered about three weeks later than plants of the cultivar Barbara when grown under natural season conditions.

3. Plants of the new Chrysanthemum had larger and more fully decorative inflorescences than plants of the cultivar Barbara.

4. Plants of the new Chrysanthemum had lighter purple-colored ray florets than plants of the cultivar Barbara.

In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plants of the male parent, the selection 93-L591002, in the following characteristics:

1. Plants of the new Chrysanthemum flowered about two to three weeks later than plants of the cultivar Barbara when grown under natural season conditions.

2. Plants of the new Chrysanthemum did not have conspicuous disc florets whereas plants of the selection 93-L591002 had conspicuous disc florets.

3. Plants of the new Chrysanthemum and the selection 93-L591002 differed in ray floret coloration as plants of the selection 93-L591002 had yellow-colored ray florets.

Plants of the new Chrysanthemum can be compared to plants of the cultivar Jambo, not patented. In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plants of the cultivar Jambo in the following characteristics:

1. Plants of the new Chrysanthemum flowered more uniformly than plants of the cultivar Jambo.

2. Ray floret color of plants of the new Chrysanthemum was slightly darker than ray floret color of plants of the cultivar Jambo.

3. Plants of the new Chrysanthemum flowered about one week earlier than plants of the cultivar Jambo when grown under natural season conditions.

Plants of the new Chrysanthemum can also be compared to plants of the cultivar Heather, disclosed in U.S. Plant Pat. No. 9,440. In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plants of the cultivar Heather in the following characteristics:

1. Plants of the new Chrysanthemum were smaller than plants of the cultivar Heather.

2. Plants of the new Chrysanthemum flowered several days later than plants of the cultivar Heather.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. The following observations and measurements describe plants grown in a fiberglass-covered greenhouse in Alva, Fla. under practices which approximate those generally used in commercial garden-type Chrysanthemum production. One cutting was directly stuck in a 15.25-cm container in November, 2001, and exposed to long day/short night conditions. Plants were pinched once about five weeks after sticking. About one week after the pinch, the photoinductive short day/long night treatments were started. During the production of the plants, day temperatures averaged about 27° C. and night temperatures averaged about 21° C. Measurements and numerical values represent averages for typical flowering plants.
